Knowing how strong your edibles are isn’t just helpful — it’s essential. While homemade infusions can’t match lab precision, a simple formula can get you surprisingly close to the real dose. Here’s how to do it, step-by-step.

Why Potency Matters

The effects of edibles are hard to guess — they hit late, hit hard, and they linger. Getting the dose wrong means sitting through hours of discomfort or feeling nothing at all.

That’s why we calculate: to avoid surprises.

What Affects Edible Strength?

• THC percentage of your cannabis
• Efficiency of decarboxylation
• Infusion method (and how well you mixed it)
• Body weight, metabolism, and tolerance
• Whether you’ve eaten recently

Even if you know your math, your body might respond differently. So always start small.

Step-by-Step: How to Calculate THC per Serving

1. Estimate THC in Your Flower

First, turn THC percentage into milligrams:

THC in mg = grams of flower × THC % × 100

Examples (1g flower):

• 10% THC → 100 mg
• 15% THC → 150 mg
• 20% THC → 200 mg

2. Adjust for Decarboxylation

Not all THCA becomes THC. A good rule is to reduce total THC by 10% after decarbing.

Adjusted values:

• 100 mg → 90 mg
• 150 mg → 135 mg
• 200 mg → 180 mg

POT by NOIDS optimizes this step — for consistent results every time.

3. Calculate Infusion Strength

Now, determine how much THC made it into your butter or oil.

Example: You decarb 1g of 20% THC cannabis → 180 mg THC post-decarb. Assume full transfer to butter: 180 mg THC total

4. Divide by Number of Servings

Take the total THC and divide by how many edibles you made.

Examples:

• 180 mg / 18 cookies = 10 mg per cookie
• 90 mg / 30 gummies = 3 mg per gummy
• 54 mg / 2.5 mg (desired dose) = ~21 servings

What’s an Average Dose?

• 2.5 mg THC – for new users or microdosing
• 5 mg THC – mild to moderate experience
• 10 mg THC – strong, not recommended for beginners
• 20+ mg THC – for high-tolerance users only

Wait at least 2 hours before deciding to take more.

Tips for Accurate Dosing

Mix Evenly

An accurate calculation means nothing if THC isn’t distributed evenly. Stir your butter/oil thoroughly before cooking or baking.

Test a Single Portion

Start with one serving and track your response. Wait, observe, then decide.

Final Note

No method is 100% perfect at home. But with good math, careful prep, and a bit of caution, you can get close enough for comfort — and avoid accidental couch-lock.

If you want repeatable results, the POT by NOIDS helps dial in each step: decarb, infuse, measure. Confidence in your edibles starts with good process.
